KANENORI 兼則 whose founder is Naoe-shizu 直江志津 school in Nanboucho period had played major role of San-ami school 三阿弥派 during Muromachi period. Some of KANENORIs had accepted an invitation from powerful regional clans and went up to major cities such as Echizen, E'chu, Owari or Shinshu domain during end Muromachi early Edo period.
KANENORI 兼則 made the great rumor being spread as Supreme Sharp Cutting performance "Yoki-wazamono" 良業物 to meet with increasing demands from brave Samurais.

The subject Tanto is created in well harmonized proportion of Mihaba to Nagasa that was designed for supplementary usage for the Katana. Hirazukuri-construction works well for cutting through the openings of armor or helmet, Itame forging ware of functional mixture with hard and soft steel is designed for durable construction.
This prominent tanto has been treasured by powerful legitimate Samurais in generations and deeply admired for the Supreme Sharp performance of the risen Mino-tradition and it still remains excellent condition over the passage of almost 500 years abounding with classical beauty.
